> Currently, sasl encryption doesn't work with AsyncRpcChannelImpl, there has 3 problems:
> 1. [sourcecode|https://github.com/apache/hbase/blob/master/hbase-client/src/main/java/org/apache/hadoop/hbase/security/SaslClientHandler.java#L308]
will throw the following exception:
> java.lang.UnsupportedOperationException: direct buffer
> 	at io.netty.buffer.UnpooledUnsafeDirectByteBuf.array(UnpooledUnsafeDirectByteBuf.java:199)
> 	at org.apache.hadoop.hbase.security.SaslClientHandler.write(SaslClientHandler.java:308)
> 2. [sourcecode|https://github.com/apache/hbase/blob/master/hbase-client/src/main/java/org/apache/hadoop/hbase/ipc/AsyncRpcChannelImpl.java#L212]
has deadlocks problem.
> 3. TestAsyncSecureIPC doesn't cover the sasl encryption test case.
